Paper Abstract

Generating a hologram by computer is essentially plotting a Fourier transform. Many of the hologram's properties are manifestations of simple Fourier mathematical relations. Although the relations are simple, finding the proper relation to explain an effect sometimes is not. The origin of this work was actually a question put to me some years ago about Fourier transforms in the context of image processing for scanning electron microscopy. The question: Why does a strong cross structure sometimes appear in an image's Fourier transform when we know that no corresponding structures exist in the object? The answer is well known, but let us delay discussing it until the next section where we explain the question's relevance to the computer generated hologram (CGH).
